7 My invention relates tjo cannons." i

It is the o'bjectof my invention to provide a construction particularlyadapted for toy cannons, toy pistols, and other toy firearms, in which afulminate cap is employed'to light a fuse of a firecrackerand'theexplosion of thel fire cracker resultsiafter ejecting the body of thefire cracker from the barrel of the gun: It is the particular object ofmy invention to provide a novel form'of breech mechanism and'firingmechanism for firing the cap, positioning the fuse of the fire crackerand lighting the fuse from the cap when itjis so positioned. r n 1 J nIt is an essential object of my invention to provide a simple structureso arranged that it must be vventilatedpositivelybetween each firing inorder'to prevent explosions,

: during loading or otherwise," prematurely due to residual gases inthe'gun, burning por- I 'tions of the 'charge,etc.

' It is my object to provide such astructure having these essentialfactors for safety and for operation, while at the sametime maintainthem with such simplicity that a child can operate them safely," andthey can 'be economically manufactured and sold for a small sum.

Referring to the drawings in detail, 1" '45 designates the trail of thegun whlch is mounted on the axle 2 to be carried by the wheels 3.

vided withan eye 7 through which passes the Y lanyard 8. v v v Mountedon' the underside of the barrel of the gun, adjacentthe breech, is ahammer block 9110 which is pivoted at 10 ahammer 11 having a hammerhead12 for' striking the firing pin 13, and a' thumb piece 14: to facilitateits being cocked. A lanyard arm '15 provided with an eye 16 is connectedto the lanyard 8 'so thatwhen the lanyard is pulled the hammer can bemoved to firing position. Within the block 9 is a springll' which servesto maintain the hammer in either firing orready to-fire positions andserves to" impel the hammer against the firing pin 13. The breech ofathegun isprovided on either pair of lateral extending which areadapted tobe lugs 18 are'sufiiciently, cam shaped on the faces 21 to form alocking engagement with the overlapping fingers 19. Thefiring pin 13 hasa head 22 which reciprocates within an open topped firing chamber23adapted to receive the fiilminate cap 24." This "chamber positions-thefulminate25 opposite the firing opening 26 into which is projected thefuse 27 of the firecracker 128- hich hasit's usual OpeTaZi Om The gun isloaded by inserting the fire crackerinto'thevbarrel withthe fuse inposition as indicated. This insertion isthrough the breech-end of the"gun. The

breech block has its firing chamber loaded with the fulniinate'c'ap. IThe bloclris 'applied'to the gun and rotated into locking.positionwith'the fuse 27 in the aperture 26.

, During this operation the'hammer and firing head are held'ininoperative position- =Upon pulling the lanyard 8 the hammer issnappedpthe firinghead drives the firing pin 13"against the fulminate25, exploding it. This in turn ignites the fuse 27 which in turn ignitesthe powder 29. The: resulting cap In a toy gun with a barrel about 6 to8 inches long, the fire cracker is ejected about 30 feet at an ordinaryelevation of the gun as indicated in Figure 2.

I desire to comprehend within my invention such modifications as may beclearly embraced within my claims and the scope of my invention. It willbe understood any means may be employed for ejecting by eX- plosion andsimultaneously igniting the charge; it will be further understood thatthe ejected charge will explode depending on the length of the fuse andthe size of the ejecting charge.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent, is:

1. In a cannon, a barrel, a cap carrying fulminate chamber independentof the barrel and means for positioning the fuse of a fire cracker insaid chamber. 7 V

2. In combination in a cannon, a barrel,'a breech block therefor, afiring chamber in said block, a firing pinand firing head in saidchamber, said chamber having a firing port and a loading port, a firinghammer adapted to engage said pin mounted on said gun, and means forpositioning a shell in said gun.

In combination, in a cannon, a barrel, a breech block therefor, a firingchamber in said block, a firing pin and firing head in said chamber,said chamber having a firing port and a loading port, a firing hammeradapted to engage said pin mounted on said gun, and means forpositioning a shell in said gun, said means being so arranged that afuse in said shell will project in said firing port. V 4. Incombination, in a gun, a gun barrel, a rotatable breech block, a firingchamber in said block having the upper end thereof open for loading, afiring pin and firing head reciprocating in said chamber.

5. In combination, in a gun, a gun barrel, a rotatable breech block, afiring chamber in said block having the upper end thereof open forloading, a firing-pin and firing head reciprocating in said chamber,said chamber having a firing port opposite-said head and means in saidgun barrel for positioning an explosion charge, shell and fuse so thatsaid fuse is located in the firing portof the firing chamber. I

6. In combination, in a gun, a gun barrel having a shell tube and abreechchamber, a rotatable breech block adapted to be located on thebreech end of the barrel and partially in saidbreech chamber, a firingchamber in said breech block having a firing opening registering withthe gun barrel to receive a shell fuse and a firing pin reciprocating insaid block with its head in said firing chamber. 1

7. In combination, in a gun, a gun barrel having a shell tubeand abreech vchamber, a rotatable breech block adapted to be located on thebreech end of the barrel, a firing chamber in said breech block having afiring opening registering with the gun barrel to receive a shell fuseand a firing pin reciprocating in said block with its head in saidchamber.

8. In combination, in a gun, a gun barrel having a shell tube and abreech chamber, a rotatable breech block adapted to be located on thebreech end of the barrel, and partly in said breech chamber a firingchamber in said breech block having a firing opening registering withthe gun barrel to receive a shell fuse and a firing pin reciprocating insaid block with its head in said firing chamher, a spring pressed firingtrigger yieldingly held in firing or cooked position. 7 9. Incombination, in a gun,'a gun barrel having a shelltube and a firingchamber, a rotatable breech block adapted to be located on the breechend of the barrel, a firing chamberin, said breech block havinga firingopening'registering with the gun barrel to receive a shellfuse and afiring pin reciprocating in said block with its head in said chamber, aspring pressed firing hammer yieldingly held in firing or cockedposition, and a lanyard for moving said trigger from cocked to firingposition. I

10. In combination, in a gun, of a barrel, a freely detachable breechblock, means onsaid breech block for supporting and igniting a firingcharge, and means in said barrel for locking a fused shell in line withthe firing charge for the ignition of said fuse, said parts being soarranged that the complete removal ofthe breech block is necessary forreloading of the firing charge whereby the gun is completely ventilatedbefore each firing operation. c 7 11. In combination, a gun barrel camlugs on the breech end thereof, a breech block plate having forwardlyand laterally projecting cam fingers engaged with said lugs to lock thebreech plate to the gun.

12. In combination, a gun barrel, cam lugs on the breech end thereof, abreech block plate having forwardly and laterally projecting cam fingersengaged with said lugs to lock the breech plate to the gun, a firingchamber and firing pin carried by said plate.

In testimony whereof I affiX my signature.

CHARLES C. BLACKMORE.
